IMPORTANT WARRANTY INFORMATION

Condensers accumulate dirt and require cleaning every 30 days. Dirty condensers result in compressor failure, product loss, and lost sales, which are not covered by warranty.

If you keep the Condenser clean you will minimize your serviceexpense and lower your electrical costs. The Condenser requires scheduled cleaning every thirty days or as needed.

Air is pulled through the Condenser continuously, along with dust, lint, grease, etc.

A dirty Condenser can result in NON-WARRANTEED part &CompressorFailures,ProductLoss,andLostSales.

Proper cleaning involves removing dust from the Condenser. By using a soft brush, or vacuuming the Condenser with a shop vac, or using CO2,nitrogen,orpressurizedair.

If you cannot remove the dirt adequately, please call your refrigera-tion service company.

On most of the reach-in units the condenser is accessible in the rear of the unit. You must remove the cabinet grill to expose the Condenser.

The Condenser looks like a group of vertical fins. You need to be able to see through the condenser for the unit to function at maximum capacity. Do not place filter material in front of condensing coil. This material blocks air-flow to the coil similar to having a dirty coil.

THE ClEANING OF THE CONdENSER IS NOT COVEREd bY THE WARRANTY!

HOW TO ClEAN THE CONdENSER:

1. Disconnect the electrical power to the unit.

2. Remove the louvered grill.

3. Vacuum or brush the dirt, lint, or debris from the finned condenser coil.

4. If you have a significant dirt build up you can blow out the condenser with compressed air.

(CAUTION MUST bE USEd TO AVOId EYE INjURY. EYE PROTECTION IS RECOMMENdEd.)

5. When finishedbesure to replace the louveredgrill.Thegrillprotects the condenser.

6. Reconnect the electrical power to the unit.

If you have any questions, please call TRUE Manufacturing at 636-240-2400 or 800-325-6152 and ask for the Service Department.DirecttoServiceDepartment1(855)372-1368.ServiceDepartmentAvailability Monday-Thursday 7:00 a.m. to 7:00 p.m., Friday 7:00 a.m. to 6:00 p.m. and Saturday 8:00 a.m. to 12:00 p.m. CST.

STAINlESS STEEl EqUIPMENT CARE ANd ClEANING

CAUTION: Do not use any steel wool, abrasive or chlorine based products to clean stainless steel surfaces.

STAINlESS STEEl OPPONENTS

There are three basic things which can break down your stainless steel’spassivitylayerandallowcorrosiontorearitsuglyhead.

1. Scratches from wire brushes, scrapers, and steel pads are just afewexamplesofitemsthatcanbeabrasivetostainlesssteel’ssurface.

2. Deposits left on your stainless steel can leave spots. You may have hard or soft water depending on what part of the country you live in. Hard water can leave spots. Hard water that is heated can leave deposits if left to sit too long. These deposits can cause the passive layer to break down and rust your stainless steel. All deposits left from food prep or service should be removed as soon as possible.

3. Chlorides are present in table salt, food, and water. Household and industrial cleaners are the worst type of chlorides to use.

8 STEPS THAT CAN HElP PREVENT RUST ON STAINlESS STEEl:

1. USING THE CORRECT ClEANING TOOlS

Use non-abrasive tools when cleaning your stainless steel products.Thestainlesssteel’spassivelayerwillnotbeharmedby soft cloths and plastic scouring pads. Step 2 tells you how to find the polishing marks.

2. ClEANING AlONG THE POlISH lINES

Polishing lines or “grain” are visible on some stainless steels.Always scrub parallel to visible lines on some stainless steels. Use a plastic scouring pad or soft cloth when you cannot see the grain.

3. USE AlKAlINE, AlKAlINE CHlORINATEd OR NON-CHlORIdE CONTAINING ClEANERS

While many traditional cleaners are loaded with chlorides, the industry is providing an ever increasing choice of non-chloride cleaners.Ifyouarenotsureofyourcleaner’schloridecontentcontact your cleaner supplier. If they tell you that your present cleaner contains chlorides, ask if they have an alternative. Avoid cleaners containing quaternary salts as they can attack stainless steel, causing pitting and rusting.

4. WATER TREATMENT

To reduce deposits, soften the hard water when possible. Installation of certain filters can remove corrosive and distasteful elements. Salts in a properly maintained water softener can be to your advantage. Contact a treatment specialist if you are not sure of the proper water treatment.

RECOMMENdEd ClEANERS FOR CERTAIN SITUATIONS / ENVIRONMENTS OF STAINlESS STEEl

A. Soap, ammonia and detergent medallion applied with a cloth or sponge can be used for routine cleaning.

B. Arcal20,Lac-O-NuEcoshineappliedprovidesbarrierfilmforfingerprints and smears.

C. Cameo, Talc, Zud First Impression is applied by rubbing in the direction of the polished lines for stubborn stains and discoloring.

D. Easy-offandDe-GreaseItovenaidareexcellentforremovalson all finishes for grease-fatty acids, blood and burnt-on foods.

E. Any good commercial detergent can be applied with a sponge or cloth to remove grease and oil.

F. Benefit, Super Sheen, Sheila Shine are good for restoration / passivation.

NOTE: The use of stainless steel cleaners or other such solvents is not recommended on plastic parts. Warm soap and water will suffice.

5. MAINTAINING THE ClEANlINESS OF YOUR FOOd EqUIPMENT

Usecleanersattherecommendedstrength(alkalinechlorinatedor non-chloride). Avoid build-up of hard stains by cleaningfrequently. When boiling water with your stainless steel equipment, the single most likely cause of damage is chlorides in the water. Heating any cleaners containing chlorides will have the same damaging effects.

6. RINSE

When using chlorinated cleaners you must rinse and wipe dry immediately. It is better to wipe standing cleaning agents and water as soon as possible. Allow the stainless steel equipment to air dry. Oxygen helps maintain the passivity film on stainless steel.

7. HYdROCHlORIC ACId (MURIATIC ACId) SHOUld NEVER bE USEd ON STAINlESS STEEl

1. This system contains R404A or R134A refrigerant and polyol ester lubricant. The polyol ester lubricant has rapid moisture absorbing qualities. If long exposure to the ambient conditions occur, the lubricant must be removed and replaced with new. For oil amounts and specifications please call TRUE technical service department (855-372-1368).Failuretocomplywithrecommendedlubricantspecificationwillvoidthecompressorwarranty.

2. Drier replacement is very important and must be changed when a system is opened for servicing. A drier using XH-7 desiccant or an exact replacement solid core drier must be used. The new drier must also be the same capacity as the drier being replaced.
